    High-Pressure Torsion to Improve Thermoelectric Efficiency of Clathrates?

    High-pressure torsion (HPT), as a technique to produce severe plastic deformation, has been proven effective to improve the thermoelectric performance of skutterudites. In this report, we present microstructur...

    Changes of Thermoelectric Properties and Hardness After HPT Processing of Micro- and Nanostructured Skutterudites

    In this paper the influence of the starting material on the physical properties after severe plastic deformation (SPD) will be discussed. A bulk p-type skutterudite DD0.44Fe2.1Co1.9Sb12(DD stands for didymium whi...

    Dependence of the Elastic Moduli of Skutterudites on Density and Temperature

    The dependency of Young’s and shear modulus on relative density and temperature was determined for three series of skutterudites: p-type MmyFe3CoSb12 (y = 0.70, 0.80), p-type DDyFe3CoSb12 (y = 0.65, 0.68) and n-t...
